1 To all 'whom it may concern.'
le it known that l, WALTER LIVINGSTON, a
citizen of the United States, residingF at Hastings, in the county of Adams and State of Nebraska, have invented a new and useful Pulley-WVheel, of which the following is a` specification.
The present invention appertains to pulley wheels, and aims to provide a novel and improveddevice of that character which is .particularlyepplieable for small pulleys,
lib
A antdamage to the machine.
such as the fan belt pulley of an automobile.
llt has not infrequently been the cause of annoyance and trouble in certain types of motor vehicles, for the pin of the fan belt pulley to become loosened, and to eut or tear the belt and. catch in the frame, with resultrJlhis invention contemplates the provision of a pulley wheel 'of unique construction,
and provided'with means for retaining-.the
locking pin in place, whereby it cannot mirage outwardly` into engagement with the beltf llt is also within'the scope of tlie invention,
to provide a pulley wheel of the nature indicated, which will be comparatively simple, non-encumbering and inexpensive in construction, which may be readilyjmanufaetured and assembled, and which will be convenient, efficient and thoroughly practical in its use.
1iWith the foregoing and other objects in view which will appear' as the description proceeds, the invention resides in the combination and arrangement of parts and in VVAthe datails of construction hereinafter dee scribed and claimed, itl being understood that changes in the precise embodiment `of the invention herein disclosed, can be made within the scope of 'what is claimed, without departing' from the spirit of the invention.
ith
poses.
The invention is illustrated in its pre ferred embodiment in the accompanying drawing, 'wher-emrv Figure l is a front view of the improved pulley wheel. Fig. 2 is a sectional view on tional View on the line of Fig 2.
ln the drawing, the numeral 1 designates the shaft, which may be taken to represent the fan shaft of a motor vehicle, although it is to be understood that the present pulley wheel may be employed for various pur- The pulley wheel is preferably pressed or otherwise formed from a blank the rim ofithe pulley wheel.
2-2 of Fig. l, and Fig. 3 is a sec-- which formsthe hub of the pulley wheel,
and the outer iiange l of which, provides curved transversely for the proper engage ment of the belt therearound. rlhe outer flange or rim 4; of the pulley wheel is preferably slightly wider than the inner flange or hub 3, and the pulley wheel 'is adapted to be slipped onto the end of the shaft l with the baelr of the pullej,T wheel disposed innermost, and so that the mouth or recess of the pulley wheel willfaee outwardly or forwardly.
The hub 3 of the pulley wheel is provided with diametrically opposite apertures 5, and the rim lof the pulley wheel is provided with diametrically opposite apertures 6 alining with the apertures 5, while the shaft l is provided with a bore or opening 7 with which the apertures are arranged to aline when the pulley wheel is slipped onto the shaft. l -tapered 'locking pin 8 is insertible through one of the apertures 6 in the rim of the pulley wheel, and into the apertures 5 of the pulley wheel hub and opening 7 of the shaft l, to lock the pulley wheel in place upon the shaft.. A ring or annulus 9 is fitted or slipped within the edge of the rim fl of the pulley wheel, and is provided with an annular eX- terior flange 'll bearing' against the edge of the pulley wheel rim 4, and projecting beyond the rim of the pulley wheel for holding the belt upon the pulley wheel. rlhe ring 9 may be secured within the edge por-4 tion of the pulley wheel rim il, by means of rivets l0, or other suitable securing means.
A resilient leaf spring l2 is bent into eircular form, and is arranged to be snapped within the rim 4l of the pulley wheel, so as to expand against the rim of the pulley wheel between the ring1 9 and the baclr'of the' the Aends desired. The retaining spring or band 12 may also be contracted and drawn outwardly through the ring 9 when it is desired to release and remove the pin 8.
'With the present pulley wheel, there is no liability of the pin becoming loosened to loosen the pulley Wheel or injure the belt, and assurance is had, that the pulley wheel vi'lll effectively serve its purpose Without Having thus described the invention, what claimed as new is v1. A pulley Wheel embodying a rim and hub apertured for the insertion of a locking pin through the rim and into the hub, and a band Within the rim for-holding the pin in place.
2. A pulley Wheel embodying a rim and hub apertured for the insertion of a locking pin through the rim and into the hub, and a resilient expansible band fitting within the rim to hold the pin in place.
3. A pulley wheel embodying an annular channel whose inner and outer flanges provide a hub and rim, respectively, the rim and hub being apertured for the insertion of av locking pin, and a band fitting in the rim for holding the pin in place.
4. A pulley Wheel embodying an annular channel whose inner and outer flanges provide a hub and rim, respectively, the rim and hub being apertured for the insertion of a locking pin, and a resilient eXpansible band fitting within the rim to hold the pin in place.
5. A pulley wheel embodying an annular channel whose inner and outer Hanges provide a hub and rim, respectively, the rim and hub being apertured-for the insertion of a locking pin, a ring engaged within the edge of the rim, and a band fitting within the rim between the ring and back of the channel.
6. A- pulley Wheel embodying an annular channel whose inner and outer flanges provide a hub and rim, respectively, the rim and hub being apertured for the insertion of a locking pin, a ring engaged Within the edge of the rim, and a resilient expansible band sprung within the rim between the ring and back of the channel.
7. A pulley Whpel embodying an annular channel whose inner and outer flanges provide a hub and rim, respectively, the rim and hub being apertured for the insertion of a looking pin, a ring engaged within the edge of therim and having a flange resting against the edge of the rim and projecting beyond the rim, and a band fitting within the rim between the ring and back of the channel.
8. A pulley wheel embodying a rim and hub apertured for the insertion of a locking pin through the rim and into the hub, and means to lie between the pin and rim for holding the pin in place.
.9. A pulley wheel embodying an annular channel whose inner and outer anges provide a hub and rim, respectively, the rim and hub being apertured for the insertion of a locking pin through the rim and into the hub, and means to lie between the pin and rim for holding the pin in place.
In testimony that I claim the foregoing `as my own, I have hereto afiixed my signature in the presence of two witnesses.
